States of America, and residing at .Cleveland, in the county of Cuyahogaand State of Ohio, have invented certain new and -useful Improvements inWinches; and we do hereby declare the following to be a full, clear, andexact descri ltion of the invention, such as-Will enable ot ers skilledin t-he art to which it pertains to make and use the Thisv inventionrelates to improvements in. Winches .and particularly in mooringWinches.

.. The requiments of n mooring Winch are marized as consisting 1ncertain novel de-` l that it notonly bring the vessel. to the dock,

but also when the vessel is alongside the dock that it hold it tightlyin place, and if vthere is any relative movement between the vessel` andthe dock due to the loading orA unloading of a cargo, the actionoftidcs, waves or-passing vessels, or if forl any other reasons thevesel rises or falls, it' is essential that.v the Winchbe able toautomatically pay out the line when the' load or vdrag in-` creasesbeyond a certainl amount to'4 avoid the breakage of the line or of the'Winch,l

again wind inthe line when it andthat it becomes slack, and therebypreserve a unlform tension on the line. Steam Winches having doublecylinder steam en es are most commonl `employed forthe a ve purpose,inasmuc as the can befoverauled or reversedwhen t 'load or dragon thelines becomes excessive and can again A wind in the lines quickly whenthey become vother motive devices'than a steam engineV slack, the steambein supplied to the cylinders continuously as ong as the Winches are 1nuse. .l

One of the objects ofthe present invention isv theprovision of anetlicient winehwhieh answers all the requirements and wherein may beemployed, such, for example, as an. electric motor. e

` i Another object is to improvegenerally the kconstruct-ion of. Winchesand to provide a Winch Which is more eiicientand economical than thosewhich have been employedv here-l tofore. 1

Incair inglout our invention We provide a winch aving. between vthe drumand the motor or motive device a friction clutch which permits the drumto turn independings k10 represents the' frame or bed of the kWinchAupon which Aall the operating parts are mounted. 1

creases beyond a certain amount, and provvide means controlled by theload for auto# matically starting or stop ingjthe motor so f that whenthe' line' is slac off, the motor Will be started and Will cause,thedrum to Wind in the line, and When the or the load falls tails ofconstruction and combinations and arts 'which will be describe inthespecification and set forth in the appended claims. l

Referring vnow to the figures of the draw- At 11 is shown a winding drumwhich is adaptedv to receive the line or cable v12, and.4

which is secured to al horizontal shaft 13 r'mounted in suitable framesor housingSfI/t carried by the bed 10. The shaft 13 has secured theretoa .large gearwheel 15 which meshes With the pinion' 16 loosely mounted lon a counter-shaft V17 which is alsov supported from the bed 10 bysuitable frames or housings 18.` The shaft 17 vis provided withV afriction clutch consisting in this case 'reference is hadto theaccompanying sheets off drawings in which-,- 8o

Thetension of the sprin 21 may be regulated by a hand' Wheel 22 aving athreaded hub 23 Which engages a threaded portion of the shaft, thespring 21 being in this case between the hand wheel andthe section 2O ofthe clutch. a

For the purpose of keeping the pinion 16' in alinenient witln ear l 1.5and 'for' the" further purpose of revu .ating the "tension of the s ring21, an adJustable nut'v 24 is provide onjthe shaft', and thisnut engagesand,
